      - `broadcast_id` integer: The identifier for a broadcast.
      - `deduplicate_id` string: An identifier in the format `id:timestamp` where the id is for the object you're working with (Automations, Deliveries, Exports, Identities, One-time sends, Segments, and Templates), and the timestamp is the last time the object was updated.
      - `name` string: The name of the action, if it exists.
      - `layout` string: The layout used for the action, if it exists.
      - `created` integer: The date time when the referenced ID was created.
      - `updated` integer: The date time when the referenced ID was last updated.
      - `body` string: The body of the action. You cannot modify the body if you created it with our drag-and-drop editor.
      - `type` 'email' | 'in_app' | 'push' | 'twilio' | 'slack' | 'whatsapp': The type of action.
      - `sending_state` 'automatic' | 'draft' | 'off': Determines the sending behavior for the action. `automatic` sends the action automatically when triggered; `draft` queues drafts when the action is triggered; or `off` to disable the action.
      - `language` string: The language variant for your message. If you don't use our [localization feature](/journeys/channels/localization/getting-started), or this is the default message, this value is an empty string.
      - `from` string: The address that the message is from, relevant if the action `type` is `email`.
      - `from_id` integer: The identifier of the `from` address, commonly known as the "sender". Use [List sender identities](/integrations/api/app/tag/sender-identities/listSenders/) to find valid IDs.
      - `reply_to` string: The address that receives replies for the message, if applicable.
      - `reply_to_id` integer, nullable: The identifier for the `reply_to` address, if applicable. Use [List sender identities](/integrations/api/app/tag/sender-identities/listSenders/) to find valid IDs.
      - `preprocessor` 'premailer': If CSS pre-processing is enabled, this key is populated with `premailer`. Note, Juice replaced Premailer as the pre-processor, but you will only see `premailer` as the value.

      - `subject` string: The subject line for an `email` action.

      - `body_amp` string: AMP-enabled content for your email. If a recipient's email client doesn't support AMP, they receive your `body` content instead. Make sure you're [set up to send AMP](/journeys/channels/email/layouts/amp-for-email/) first.
      - `campaign_id` integer: The identifier for an automation.
      - `parent_action_id` integer: The ID of the parent action, if the action occurred within an automation and has a parent (like a randomized split, etc).
      - `multi_language_branch_action_id` integer: Returned when the action is a language variant of a multi-language message. This id is the same for each variant of a message, so you can use this to retrieve metrics for a message and all its variants.
      - `headers` string, json: A JSON string containing header objects with `name` and `value`. Names and values must be strings, with no non-ASCII characters or spaces. You can't overwrite reserved headers.
